Application -aied aaaary 5,- 19oa serial No.l 476,749.

To allwhom it may concern." i g Be 1t known that I, THoMAsCoNsEisTINO,

` a citizen of Italy, residingatHouston-,inthe county Of-Harris and State of"Texas, have invented certain new and useful-Improve- -ments in Firearms, of which `the following is a specification.

My invention" relates to'new and useful,

improvements in rearm's, and more particularly to that class of such .devices as auto- .matically eject the empty cartridge shell and placev the cartridge to be fired inV position 'i for discharge.

The object of t-heinventionvistoprovide out injury to any of the parts. As is well known, the devicesof this character, now in common use, are held together by means of screws, pins etc.,"which must be 'removed whenever 1t becomes necessary to take the lsame apart, for cleaning or other purposes, and the delicate parts of the mechanism'thus soon become'battered and worn so that the for locking the guard .back when the magazineis empty, or removed.

A still furtherifeature resides in thel prol vision of a -novelly -constru'wcd magazine,

which holdsmore cartridges than magazines.

of equal size and which holds thecartrid'ges compactly together .and automatically brings4 each cartridge in its turn, into position ,for

being acted" upon by the mechanism, de-` signed to bring the same into positionfor discharge. A still further feature of my invention i consists of means for discharging the cartridge shell.

Flnally the object of the invention is to provide a device-of the character described,

that will be compact, practical, and one'that can be readily taken apart and readily. put

'i together and one in which theseveral parts `willnot be likely to get out of working order.

"With theA above and other objects in view, my invention has' particular relation to certain novel fea-tures of constructionand operation, lan example of which is given 1n r35 this specification; whichjl do declare to be a a device of the character described that may be readily taken apart and put together, withinvention, reference being had to the accompanymg drawings, and characters of designation marked thereon, which are made a part hereof and wherein,

AFlgure 1 is a side'elevation `of the firearm complete.v Fig.,.2 is a sectional view, thereof. taken on the'line a-a of Fig. 3. Fig. 3 1s a' rear elevation View. Fig. 4 is an end view of the muzzle.' Fig. 5 is a side elevation of the barrel.` Fig. 6 is a side elevation of the frame of my invention. Fig. 7 shows sldeelevation and edge views of one; ofthe grips. Fig. 8 shows side elevation and edge views of the other grip. Fig. 9 shows a side elevation of the plunger. Fig. l0 shows side elevation and plan View of the ringpin. Figs. 11, 12, and 13 show forms and method Ofoperation of pull springs which are designed to be placed in the magazine to hold the cartridges in position. Fig. 14`shows a key-pin designed to secure the parts together. Fig. 15 shows a plan View of the release button, andfiring pin. Fig. l16,

shows a plan view of the hammer and firing pin. Fig. 16a is-a sectional view of the arm taken on 'the line b-b of Fig. 17, and Fig. 17 is an enlarged, partial, sectional view of the operative mechanism taken on the line .ct-a of Fig. ,3. Fig. 18 is an enlarged par tial sectional view showing the operative relation of the co-actlng parts and with the arm in the ac tof ejecting the cartridge hull. Referring now more particularly to the drawings, wherein like numerals of-referl2g6- ence designate similar parts, in each of the figures, the numeral lrefers to the barrel, which is shown in complete detail 1n Fig. 5.

This barrel extends the full length of the arm and is provided near its rear portion 'with a shoulder 2. It is also provided with oppositelydisposed slots and 11g-near its rear end, the former of which is in its upper side and provided'for the ejectlonof the shelltherethrough and the other of which is designed to -permit the entrance of the loaded cartridge therein.. -Thevbarrel is also provided with a transverse open ended slot 5 in its rear end fora `purpose hereinafter sot forth. g l

The numeral 6 refers to the frame which is preferably composed lof sheet metal and comprises, in general, the magazine chamber, trigger guard, and barrel Support, andas shown dismembered and' detail in'Fig clear, exact and complete `description .of my titl The numeral 7 designates the barrel casing which carries the usual sight and bead, located as in an ordinary firearm; this casing is of a shape and size to tit snugly overv the barrel and is substantially semi-cylindricalin shape, a complete longitudinal section ofthe cylinder having been removed. The edges of this casing are tongued and grooved in any suitable manner sov as to dove-tail with the similarly .constructed edges of the barrel support of the frame 6, as shown in Figs. 3 and 4, and is further provided with a discharge opening 8 of a size and shape to permit of the passage of the shell therethrough. This casing lis de signed to slide back and forth on its support, and carries an inward shoulder -9 near its muzzle 'end and the breech thereof rests upon the shouldered portion 2 of the barrel, as shown in Fig. 2, thus providing an annular space 10 between the casing 'and barrel, in which the main Spring 11 operates. This spring is made preferably of elastic wire suitably coiled and operates against both shoulder 2 of the barrel and shoulder 9 of the easing, thus holding the easing in the position, in regard to the barrelshown inl Fig. 2, which may be called its normal position. Near its end the casing 7 is provided with two diametrically opposed transverse openings 12 alined with the slot 5 of the barrel 1 designed to receive key-pin 13 shown in Fig. 14. This pin 13 plays also through slot' and While permittlng free rearward movement of the casing 7 limits the forward movement thereof. This pin isflat on two sides and slightly wedge shaped so that it Will bind'enough to be held firmly in position.

Within the'rear portion of the barrel 1, a cylindrical breechbolt 14 operates. This breech-bolt is shown more in detail in Fig. 9 and is provided with suitable lugs 15 which radiate therefrom and protrude into oblong slots 5 in the rear end of the barrel and close the same against dust, etc. The breech-bolt 14 is further provided with an oblong longitudinal slot 16 through which key-pin 13 passes and by which the for! ward and rearward movementiof the breechbolt is limited relative to the casing 7. This breech-bolt carries atfits forward end an extractor 17 designed to engage over the rim i of the cartridge as shown in Figzl and cxi tracts the cartridge when the said cartridge fails to lire and the easing is pulled back bv the hand. rThe breech-holt 14: is tubular and l within it a -hammer 1S plays. 'lhe back ot extractor 20 is provided with a shoulder 41. i 'lliis hammer is oblong in shape and designed to lit snugly within the breech-bolt and is secured therein by means of key-pin 13 passing therethrough. l't is obvious that i the play of the hammer relative to the breechbolt willl be equal to the length ofl slot 16 and as key pin 13 passes'l snugly through the openings 12 in the casing and also through a similar opening in the hammer, the hammer has no movement independent of the casing but moves back and forth therewith. The fore end of the ham' mer 18 has a longitudinal slot for carrying a firing' pin-19. This tiring pin carries a` projecting shoulder 20 on its underside and near its front end designed to engage in a transverse slot 25 i'n the under side of breechbolt 14, which engagement is normally secured by means of a downward pressure of spring 21, against said firing pin. This spring is carried by said tiring pin and is preferably made of spring steel. The hammer and firing pin are jointly of such a length that when the hammer is driven in a manner hereinafter described the pin will stri-ke the cap or primer of the cartridge and cause the same to be discharged. This tiring pin has free vertical play in the hammerpbut its rearward motion is limited by the hammer 18 and it carries shoulder l22 on its sides which limit its forward motion by coming into contact with opposing shoulder,4t1 carried by the hammer 18 and thus it is prevented from falling out of the hammer and plunger.

lVithin the trigger guard of Fig.I 2 l have provided a trigger 23. This trigger rests against aiat. curved spring 24 whose convex side rests against said trigger. This springl is secured to the trigger guard at its lower end by a hook carried by said spring and its upper end is alined with slot 25 and, when in its normal position is barely withjdrawn therefrom. A pull on the trigger Will thus elevate the freez end of the spring 24 land carry the shoulder 20 of the firing pin 19 out of engagement with the side of slotI 25 and leaves the tiring pin free to be driven forward by the action of hammer 18.

The downwardly extending portion of trame G which is preferably made of sheet steel. constitutes, also, the frame work of the handle of my invention. This handle is designed to contain magazine 26 of the'arm. This magazine is held in place by means of catch springs 3l in the usual manner. 'lhese catch springs may be released by pressure y upon the thumb buttons 27 and the magazine` removed for loading or for any other purpose. This magazine is provided with a plurality of pull springs 2t; within the same. preferably three in number, two 'of which are located ou one side thereof, and one of which is located on the other side. 'llllese pnll springs engage at their upper ends`over the upper edges of the n'nagazine andare del signed to embrace the cartridges 29 as shown in 'Figs. 2 and 13 and to keep them elevated so as to be engaged by the breech-bolt when in its forward thrust and thus brought in position for discharge. These springs are y flat, ribbon-like springs and coil at their botvio ' inwardly extending' tlanges'to prevent the release of lcartridges' except by forward thrust of the breech-bolt; and in front of these flanges it carries two wings 42, one on either side, which .stop the shell that is to be" ejected.

In Figs. 7 and 8 I have shown mypreferred form of grips designated respectively, by the numerals and 31. These grips are made of rubber or other suitable material and are secured to the frame. 6 by projecting lugs 35, gaged over the edges 36 of the frame work and then forced downward until said engagement is secured. `The grips should be Y placed in position before the casing 7 is placed on the weapon, and when the casing is placed in position it will engage over the upwardly extending lugs 32 and secure the grips, gainst upward movement; and thus prevent the 'disengagement of the inwardly projecting lugs. Thus the grips will be securely held in place.

Frame ,6 carries -an oblong'sheet-steel spring 37, integralv therewith at its lower end but whose upper end is free. This spring, as is obvious is capable 4of limited transverse movement, and its Vupper Aor free end normallyl rests in notch 38 of casi-ig 7.

A rclea se button 39, shown also in Fig. 15, is carried by grip 30. This button rests against spring| 37 and protrudes through said grip; lt is held in proper position by means of said spring and lugs extending laterally therefrom lin'iitits outward protrnsion. The engagement. of this spring 37 withv'notch 38 of casing 7 holds said casing against forward or backward movement; but by a pressure on releasebutton 39 this spring may -becarrie'd out of engagement with notch 38 of said casing. and, if. at the same tinxe. the shoulder 20'of the tiring pin lf) is released from its engagementiu slot.,

by a pull on trigger 23, the casing will-"be,

carried forward, by the' action of main springl l0, carrying with it lian'inicr 18 and tiring pin 19 and the cartridges willbe discharged. Ttwill thus be' seen that, the pull i on the trigger. and the pressure upon the release button 39 must be' simultaneous` or the weapon will not be discharged, and thus a safety weapon is provided.

It will vbe readily observed that by ,the removal of key-piiilB, the casing 7 maybe re-l carried by said grips, which are en` moved and when the same is removed the barrel and grips are left free to be taken oila and all t-le other parts may then in turn be dismembered, and this process may be reversed and all oftheparts will be secured together and held in proper position by means of key-pin 13.v Thus I have dispensed with the necessity of screws, keys, etc., with the singlev exception of pin 13.

The weapon herein describedoperates as follows :4When the weapon isl loaded as shown in Fig. 2 and shoulder 20 of tiring pin 19 is engaged in slotl 25 of breech-bolt 14 and the free end of spring 37 is engagedA in notch 38 of casing 7, a pull upon trigger 23 and a simultaneous pressure upon release button 39, will release casing 7 to the action of main spring 10 and the forward thrust ofsaidvcasingwill operate to discharge the weapon as above set forth. The recoil will carry said breech-bolt back entirely in the rear of the magazine but the extractor 17 will firmly hold the shell o'f the'discharged cartridge until it comes in contact with'the win s 4'2 carried by the magazine. It is to be o served that'the upperend of spring 24 is to be made very elastic so as to readily yield to the rearward movement -of the breech bolt, in case said spring is not entirely withdrawn from the slot 25 at the instant of recoil, and thus a locking .of the breech bolt against recoil is avoided. The upper end of this spring may also be rearwardly beveled, and that portion of the breech bolt contacting therewith, in the recoil movement, correspondingly beveled, as shown in Fig. 18as a further precaution against the locking of the mechanism at the instant of recoil. comes linto contact with said wings, the discharge opening 8 of casing 7 coincides with slot 3 of the barrel 1 and by reason of the rearward jerk of extractor 17 exerted on said shell, the shell is ejected jrrom the weapon and at the same time the next car.-l

tridge is pulled upward by its pull springs ,28 through slot 4 of the barrel as faras the inwardly `extending flanges of the magazine will permit` it and the breech-bolt continues `its rearward course until the shoulder 41 of extractor 17 touches the rear end of the barrel .at the point 42 Fig. 18, by which it is stopped, but the giard and hammer, by rea son of the momentum imparted to them from the force 'of the explosion, are carried farther back until the key pin 13 touches the rear end of the slot of the breech bolt, when the shoulders of the firing pin engage in* the At the time the shell slot carried on the underside of the breechbolt, and the force of the recoil then hav-v ing been spent the actionof main sprino 10 operates to again carry the casing 7 and its breech-bolt forward. As the breech lbolt moves forward it engages with the rear end ofA the next succeeding cartridge whichis iso' shoved forward into the chamber of the barrel, extractor .17 at the lsaine time engaging with the cartridge rim.

An inwardly extending spring 40 carried by frame 6 and integral therewith extends up within the barrel 1 and is disposed to press against the magazine. When the magazine'is removed the spring 40 meets ,with no resistance from within and, consequently projects into the path of the plunger and engages with the front end-thereof; and the guard and plunger are thus` locked back and the weapon is left open. When the magazine is in place, but empty, its rear p ull spring-projects into the path of the plunger and'locks it back as above described and notice is thereby given thatthe cartridges have been exhausted from the magazine.

A weapon constructed as above described Iwill not only be a safety and automatic weapon but will'be found compact, practical and, readily taken' apart 4 and secured together. A
